I upgraded from 8.0.14 to 8.3.2. Beforehand, file copies often took a
long time and would even pause for several seconds mid-copy. dd would
hardly work at all. After the upgrade, now I get 111MB/sec when using dd
to create a file on the drbd volume. I'm very excited about that.

Only question: I did the upgrade by simply stopping drbd, building from
source, and restarting drbd. I did the secondary node first, then made
it primary, then did the other node.

After doing the upgrade, then I belatedly wondered if I would run into
compatibility problems with the metadata or something. Everything seems
to be working great. Could there be any issues with the way I did the
upgrade?
